A Companion Post to the Dragon Photos Below
From The Voyage of the Dawn Treader by C. S. Lewis:
…Eustace had read only the wrong books. They had a lot to say about exports and imports and governments and drains, but they were weak on dragons. That is why he was so puzzled at the surface on which he was lying.
So you should read some dragon books. In case you end up in dragon’s lair, like Eustace did.
